Mercy is clemency and forbearance; mercy is the disposition to forgive or show compassion; mercy means a favor or a blessing; mercy further denotes the qualities of kindness, sympathy, generosity, and beneficence. Suffice is to say that all of these qualities were present in abundance in the character of the Prophet Muhammad (May Allah have his peace and blessings on him).
He was a mercy not just to believers, but to disbelievers as well, for he would invite them to come out of darkness and into the light of true guidance. He is a favor and blessing for mankind, not just the Arabs, the people among whom he was sent, but for people of all races and colors. His staunchest enemies became his closest followers when the cloud of blind prejudice was removed from their sight and when they were able, for the very first time, to see with clarity the true nature of the Prophet's character.
This book deals with many of the qualities that the Prophet possessed that made him the mercy to everyone. It starts with His perfect lineage, His noble upbringing, and his fully dedicated worship. This book then gives many of the qualities of the Prophet including his generosity, humbleness, bravery, patience, and leadership to name a few. Each chapter includes examples from the life of the Prophet on how he was the perfect living example of that quality. The book ends with the perfection of life of the Prophet with his farewell sermon and even his noble death where he demonstrated some of those qualities as well.
